In the southern United States, bad storms have killed at least 18 people and put millions more under tornado watch.

Over the Memorial Day weekend, a tornado killed people and destroyed homes and power lines in parts of Texas, Oklahoma, and Arkansas.

The Associated Press reports that a tornado in Cooke County, Texas, caused at least seven deaths in an area near a mobile home park.

Twenty people were hurt in the area by the severe storms, according to Ray Sappington, sheriff of Cooke County.

After some time, the sheriff confirmed that two children, one 2 years old and the other 5 years old, were among the dead.

That number is likely to go up, Sappington told reporters, “even though we know for sure that five people are dead.”

“This house is empty.” It’s just a path of broken things. The destruction is pretty bad.

The news source also said that officials in Oklahoma and Arkansas confirmed four deaths, with two in each state.

A tornado stopped traffic in Denton County, Texas, and 18-wheeler trucks were seen flipping over.

Several dozen more people have been hurt by the severe storms, and between 60 and 80 people are trapped in a Shell gas station in Northeast Texas.

Sappington told CNN that many people were hurt, but none of them were seriously hurt.

A wedding held outside in rural Woods County, Oklahoma, also caused multiple injuries.

Pictures of the storm damage show broken power lines, wrecked cars, and homes and buildings that have been torn apart.

The Lake Ray Roberts Marina in Sanger, Texas, said on social media that the storms did a lot of damage to their property.

The harbor wrote, “There is so much damage that we don’t even know where to start.”

The post said that most of the RVs in the area had been turned over with people inside, and that the fuel dock, boats, and boat houses were badly damaged.

All of the people were saved, and no injuries were reported.

They also said that their dock cat Ginger was lost in the storm.

“Our hearts are broken but we were watched over by our Lord and Savior last night,” they added.

“Today we are blessed and grateful.” Say prayers for those who didn’t have as much luck as we did.”

The bad weather happened just a few days after a tornado killed five people in Iowa and caused a terrible path of destruction.

As of Sunday, there were tornado watches in some parts of Kentucky, northern Tennessee, and southwest Indiana.

Authorities say the bad weather could include “a couple intense tornadoes” and damaging winds of up to 75 mph.

Storm Prediction Center of the National Weather Service says there could be “multiple rounds of severe storms” over the Mississippi and Ohio Valleys. Tornadoes, hail, and strong winds are all possible.

Indianapolis, Indiana; Memphis, Tennessee; Nashville, Tennessee; Cincinnati, Ohio; and Louisville, Kentucky are some of the most important cities in the at-risk area.

Poweroutage.us says that hundreds of thousands of Americans are still without power.

Kentucky had more than 164,000 people without power by Sunday afternoon. Arkansas had more than 102,000, and Texas had more than 55,000.

CNN says that the severe stormy weather will likely keep moving east over the next few days.
